3.6 PRE-TESTS AND TESTS

A. Pre-test the elevators and related equipment in the presence of the

Resident Engineer or his authorized representative for proper operation

before requesting final inspection. Conduct final inspection at other

than normal working hours, if required by Resident Engineer.

1. Procedure outlined in the Inspectors Manual for Electric Elevators,

ASME A17.2 shall apply.

a. Final test shall be conducted in the presence of and witnessed by

a third party ASME QEI-1 Certified Elevator Inspector, contracted

by the VA.

08/01/16

14 21 00-46

b. Government shall furnish electric power including necessary

current for starting, testing, and operating machinery of each

elevator.

2. Contractor shall furnish the following test instruments and

materials on-site and at the designated time of inspection: properly

marked certified test weights, voltmeter, amp probe, thermometers,

direct reading tachometer, megohm meter, vibration meter, sound

meter, light meter, stop watch, and a means of two-way

communication.

B. Inspect workmanship, equipment furnished, and installation for

compliance with specification.

C. Balance Tests: The percent of counterbalance shall be checked by

placing test weights in car until the car and counterweight are equal

in weight when located at the mid-point of travel. If the actual

percent of counter balance does not conform to the specification, the

amount of counterweight shall be adjusted until conformance is reached.

D. Full-Load Run Test: Elevator shall be tested for a period of one hour

continuous run with full contract load in the car. The test run shall

consist of the elevator stopping at every floor, in either direction of

travel, for not less than five or more than ten seconds per floor.

E. Speed Test: The actual speed of the elevator shall be determined in

both directions of travel with full contract load and no load in the

elevator. Speed shall be determined by applying a certified tachometer

to the car hoisting ropes or governor rope. The actual measured speed

of the elevator with all loads in either direction shall be within

three (3) percent of specified rated speed. Full speed runs shall be

quiet and free from vibration and sway.

F. Temperature Rise Test: The temperature rise of the hoisting motor shall

be determined during the full load test run. Temperatures shall be

measured by the use of thermometers. Under these conditions, the

temperature rise of the equipment shall not exceed 50 degrees

Centigrade above ambient temperature. Test shall start when all machine

room equipment is within five (5) degrees Centigrade of the ambient

temperature. Other tests for heat runs on motors shall be performed as

prescribed by the Institute of Electrical and Electronic Engineers.

G. Car Leveling Test: Elevator car leveling devices shall be tested for

accuracy of leveling at all floors with no load in car and with

contract load in car, in both directions of travel. Accuracy of floor

08/01/16

14 21 00-47

level shall be within plus or minus 3 mm (.125 in.) of level with

landing floor for which the stop has been initiated regardless of load

in car or direction of travel. The car leveling device shall

automatically correct over travel as well as under travel and shall

maintain the car floor within plus or minus 3 mm (.125 in.) of level

with the landing floor regardless of change in load.

H. Brake Test: The action of the brake shall be prompt and a smooth stop

shall result in the up and down directions of travel with no load and

rated load in the elevator. Down stopping shall be tested with 125

percent of rated load in the elevator.

I. Insulation Resistance Test: The elevator's complete wiring system shall

be free from short circuits and ground faults and the insulation

resistance of the system shall be determined by use of megohm meter, at

the discretion of the Elevator Inspector conducting the test.

J. Safety Devices: Car and counterweight safety devices shall be tested.

K. Overload Devices: Test all overload current protection devices in the

system at final inspection.

L. Limit Stops:

1. The position of the car when stopped by each of the normal limit

switches with no load and with contract load in the car shall be

accurately measured.

2. Final position of the elevator relative to the terminal landings

shall be determined when the elevator has been stopped by the final

limits. The lower limit stop shall be made with contract load in the

elevator. Elevator shall be operated at inspection speed for both

tests. Normal limit stopping devices shall be inoperative for the

tests.

M. Oil Buffer Tests: These tests shall be conducted with operating device

and limit stops inoperative and with contract load in the elevator for

the car buffer and with no load in the elevator for the counterweight

buffer. Preliminary test shall be made at the lowest (leveling) speed.

Final tests shall be conducted at contract speed. Buffers shall

compress and return to the fully extended position without oil leakage.

N. Operating and Signal System: The elevator shall be operated by the

operating devices provided and the operation signals and automatic

floor leveling shall function in accordance with requirements

specified. Starting, stopping and leveling shall be smooth and

comfortable without appreciable steps of acceleration or deceleration.

08/01/16

14 21 00-48

O. Performance of the Elevator supervisory system shall be witnessed and

approved by the elevator inspector and a representative of the Resident

Engineer.

P. If equipment fails test requirements and a re-inspection is required,

the Contractor shall be responsible for the cost of re-inspection;

salaries, transportation expenses, and per-diem expenses incurred by

the elevator inspector and representative of the Resident Engineer.

3.7 INSTRUCTION OF VA PERSONNEL
